Re: [tpop3d-discuss] fork_child: fork: Not enough space

[Michael Klatsky]

Here is a typical "top":

last pid:  4933;  load averages:  0.25,  0.45,  0.54 
       10:07:53
203 processes: 202 sleeping, 1 on cpu
CPU states: 11.3% idle,  6.2% user,  7.1% kernel, 75.4% iowait,  0.0% swap
Memory: 2048M real, 581M free, 1331M swap in use, 669M swap free



And a brief output of vmstat 10 (formatting came out terrible):

This server runs postfix, tpop3d, apache and ldap (used only for 
postfix- tpop3d points to another ldap replicated server). The total 
number of mail users is around 3,000. This machine also has 4 cpu's (e450).

Thanks again for the quick response!
