Memory allocation failure

[Carme Torca]

Hi,

I have this messages at the syslog:

ftpd[14842]: Memory allocation failure
vmunix: Deferred swap reservation failure pid: 14681


I have a system L2000-36 with 4 GB of Memory Physical and 4GB swap.

Maybe I need to incresed the swap and decrese dbc_max_pct???

Thanks!
Carmen.

Well, you've definately run out of swap and your simplet appraach is to increase it. You might want to consider increasing physical RAM too.
