Upgrading from 2.4.3 to 2.4.4 new error in logs



  • Hello,

    I had a bit of trouble with the upgrade ... the system ran out of disk space for some reason - there was over 32GB free. I was able to recover the system and everything is fine.

    However, I see the following error in the logs now:

    sonewconn: pcb 0xfffff800949803a0: Listen queue overflow: 8 already in queue awaiting acceptance (1 occurrences)

    This is repeated over and over from time to time.

    I'm running in an ESX virtualized environment.

    I see on other FreeBSD forums that this maybe related to the kern.ipc.somaxconn setting - increasing it should fix the issue? Any problem following this advice and increasing kern.ipc.somaxconn to 4096 as recommended on the FreeNAS and FreeBSD forums?

    Thanks.

    What packages do you have running?

    Are there a lot of clients hitting services on the firewall itself?

    That is probably referring to a UNIX socket, not a TCP socket, so the tunable probably won't help.



  • I didn't run out of space during the upgrade, but I have been intermittently seeing something similar since moving to 2.4.4:

    sonewconn: pcb 0xfffff801615fdcb0: Listen queue overflow: 8 already in queue awaiting acceptance (1 occurrences)

    I'm using this in a home environment on a mini PC, but there isn't really much running in my network. FWIW, bumping up kern.ipc.somaxconn from the default of 128 to 256 hasn't changed anything, which would seem to reinforce jimp's assertion. Other than this error being in the log, I haven't noticed any other errors or performance problems.
