Description Vitezslav Novy 2001-11-28 15:40:01 UTC

if kern.maxproc > 512 (MAXUSERS>30 in kernel configuration)  sybase ASE 11.9.2(linux binary) exits on signal 11

Similar to PR kern/8607, which was closed without solution,
but behavior is affected by value of kern.maxproc.
Changing value of kern.maxprocperuid has no effect.

Here is eroor message form log file:

Comment 1 Vitezslav Novy 2001-12-27 15:44:52 UTC

Correction: 
behavior depends on kern.maxfilesperproc which depends on kern.maxproc.

Sybase server is unhappy when it is allowed to open more then 1024 files.

So setting this limit for sybase daemon user in login.conf
or 
limits -n 1024 
when starting server seems to be good work-around.
