Too Many Open Files

Support

So everything is mostly stuck on database operations, and I suspect the database is stuck on this:

goroutine 35 [syscall]:
syscall.Syscall(0x4a, 0x12, 0x0, 0x0, 0x4a6f22, 0xc423913228, 0xc423913230)
    /usr/local/go/src/syscall/asm_linux_amd64.s:18 +0x5
syscall.Fsync(0x12, 0xd49338, 0xc424280000)
    /usr/local/go/src/syscall/zsyscall_linux_amd64.go:473 +0x4a
internal/poll.(*FD).Fsync(0xc424280000, 0x0, 0x0)
    /usr/local/go/src/internal/poll/fd_posix.go:56 +0x88

It doesn’t say that it was stuck on fsync for a long time, so perhaps the fsync is returning fine, but perhaps the database is in a bad state where it must do a lot of compaction, and the compaction is taking a while, triggering the deadlock timeout. Is the database on some network share or something like that? If it’s not a lot of data you have there, perhaps you can try resetting the database.

The fact you are getting deadlock timeouts is just a side effect of running a development build. I am on the phone and can’t check if there is a way to disable it.

Hi Audrius:

Many thanks for your input on this.

The database is on the same RAID set as the data files themselves - so I would expect it to be solid, but not necessarily very fast. Unfortunately I have a very large data set, so resetting the database is not an ideal option… And putting the database on a separate, fast, drive is not going to be easy either.

Indeed - and giving the STDEADLOCKTIMEOUT=7200 variable has been good on previous builds to work around the slow database response - but for some reason, this time it’s kicking off this deadlock problem and prompting syncthing to restart (and not write a panic log, IIRC).

I’ll try running this build with the STDEADLOCKTIMEOUT variable on another system, and see if I get the same result. At least I can eliminate the hardware as a factor then…

Thanks,

Pants.

Yeah, I suspect @calmh’s recent env var cleanup made it so that non-release builds always run either with 20min deadlock timeout, or lock order deadlock detector.

I don’t know how calmh produced the build for you, but he potentially needs to remove the deadlock detector on it.

78

I’ll make a new one tomorrow on the current master. It’s just a few extra debug prints to hopefully figure out where those stopped syncs stop.

79

Thanks Jakob - that would be really appreciated!

Here’s a new build:

https://build.syncthing.net/viewLog.html?buildId=15155&buildTypeId=Syncthing_BuildLinuxCross&tab=artifacts

It has the automatic deadlock detector thing disabled. Do not set any deadlock related envvars (or you will wake it again). Do set STTRACE=model though.

What a gentleman - many thanks!

Hi:

A brief update: I’ve been running the new build since yesterday, and it hasn’t panicked yet - thanks for a build that’s working in this respect! Unfortunately a bunch of files got moved around in the shared folder, so it’s currently reconciling those before starting the transfer again - I don’t yet have any further logs to forward you.

Thanks,

Pants.

Hi Jakob:

I’ve uploaded a copy of the current trace file (to ‘Too Many Open Files 4’); unfortunately there’s a lot of noise in there from where a bunch of files have been moved around - sorry. It’s a 900MB file (sorry!) - I wanted to make sure there’s enough in there, alongside all the noise.

I found a series of entries which reflect the same situation as I previously highlighted - a transfer seemingly ending early. In this case it seems to have picked up again a short while later - but I can’t see any evidence of the last few blocks being transferred:

So far the system hasn’t panicked (and only has 125 file descriptors open), so I can’t provide a panic log from this build. I suspect this is because it’s spending so much time reconciling the file movements.

I hope that’s of some use - please let know if there’s anything else I can provide to help.

Best wishes,

Pants.

Try this build: https://build.syncthing.net/viewLog.html?buildId=15399&buildTypeId=Syncthing_BuildLinuxCross&tab=artifacts

No need for tracing and stuff, just use it in normal operations and see if the number of open files stays low enough and it doesn’t crash…

Thanks Jakob - that’s amazing! I’ll try it and report back.

Words can’t adequately describe how fabulously supported this project is - it absolutely puts many commercial operations to shame. My deepest gratitude to - in particular - @calmh and @AudriusButkevicius for their support through this.

Hello:

To follow up on this: I haven’t yet had a panic since installing the new build - thanks!

However I’m having some curious issues with the setup now - I’ll start a new thread for those.

I think I have the same, bug the Gtk client quits with can’t open socket too many open files.

I’m on Ubuntu 17.10 using the deb recommended from the site. Is there going to be a release with the fix.
