tcpd_thread_create: thread_create failed:12 error

Hi there --

I was doing a check of the dmesg output on our HP-UX 11.11 server, and the following entries were discovered there:

WARNING: tcpd_thread_create: thread_create failed: 12
kthread: table is full

The server does not appear to be operating abnormally, and I wanted to know what the above errors mean, and what needs to be done to correct them.

The server itself is an RP3440 risc system running, as mentioned, the HP-UX 11.11 distribution. The server is part of a two-node ServiceGuard cluster. It runs as an NIS master server, and is also running Samba and Postgres daemons. The server in question was recently upgraded with a cumulative patch medium installation.

If there is any further detail needed, please let me know. Thanks.

Re: tcpd_thread_create: thread_create failed:12 error

Hi Andrew:

You might have a look at the kernel parameters 'nkthread' and 'max_thread_proc'. These are documented in the 11.23 manpages (section-5) and I believe will guide you in 11.11.

On 11.11, use 'kmtune' to view and/or set kernel parameters.
