Subject Linux Semaphores and Classic

Hi,

We are using Classic server 1.52 on a Linux 8 Gb dual CPU opteron 242
with Windows clients. There are about 110 users with 450 connections
at peak times. Currently our database has about 600 tables and is 14Gb.

Up until recently we were getting database page errors every day. The
database would be backed up and restored at the end of the day but
there would be more database page errors the next day. All of our
applications make use of "temporary tables", that is, tables that
are created and dropped at runtime. Recently, we increased the Linux
semaphore count and the page errors have not reappeared. Is it
possible that increasing the semaphore count could do this?
