Thanks, I presume pf and altq are running on this machine.
How many request per second do you have?

=46rom source, httpd-2.0.53/server/mpm_common.c ;-)

Does sysctl oid net.inet.ip.intr_queue_drops increase when these=20
warnings occur? if yes:
- increase net.inet.ip.intr_queue_maxlen to see if it solve the=20
  problem or limit the rate of error.
- does apache compiled  with WITH_KQUEUE_SUPPORT fix the problem?

OTOH, it can come from you sslmutex configuration  which may prevent=20
apache to work correctly in a jail.


I'll give a try when I have some free time, thanks for the reports.
