Description Henrik Friedrichsen 2008-07-20 16:40:00 UTC

After a few days of uptime of Apache 2.2 and FreeBSD, Apache 2.2 stops accepting new requests. Looking at netstat, there hundreds of connections with a CLOSED_WAIT state. Apache 2.2 is running the worker module.

I'm using if_re, which has caused problems before (wrong tcp checksums), we then used the patched files posted on the mailinglist by a FreeBSD comitter.
After restarting apache, the problem is solved until it reoccurs.


dev.re.0.%desc: RealTek 8168/8111B PCIe Gigabit Ethernet
dev.re.0.%pnpinfo: vendor=0x10ec device=0x8168 subvendor=0x1462 subdevice=0x368c class=0x020000


Thanks a lot,
Henrik.

tree? Thanks for your report.

Hey,

it turned out to be a problem with the if_re driver which I have "bypassed"
by turning off these options with ifconfig: rxcsum txcsum tso lro vlanhwtag

Additionally I have applied Pyun YongHyeon's patches for if_re.
So far things are stable if I run apache2.2 with the prefork MPM.

Henrik.
