Dear Björn,
The error indicates that /pthread_create /returned EAGAIN
(paraphrased as "Resource temporarily unavailable").
This error indicates that
"the system lacked the necessary resources to create
another thread, or the system-imposed limit on the total
number of threads in a process {PTHREAD_THREADS_MAX}
would be exceeded. " (from http://linux.die.net/man/3/pthread_create).
so, for the user, under which the server runs, check "ulimit -u",
limits.conf, etc. Can it be that you switched to a new machine with lower
limits than before?
What is you setting of maxthreads?

Hi,
After recently upgrading from AOLserver 4.5.0 to 4.5.1 and from
nspostgres-4.0 to nspostgres-4.1 the server is repeatedly crashing
(when it gets hammered by the google bots). The error.log has many
entries like these before the server dies:
[17/Nov/2010:02:18:42][700.3218660208][-default:6195-] Notice:

The server is running on Ubuntu 10.04.1 LTS
2.6.32-25-generic-pae #45-Ubuntu SMP Sat Oct 16 21:01:33 UTC 2010 i686
GNU/Linux
Is there anything I should configure differently or has any other
ideas what might be causing this?
