this is not about caps, but limits that prevent creating new tcp
(mysql) connections. Might be even mysql server limits (how many new
connections per second it accepts). I was not able to identify the
limits, that's why I added those delay parameters.<br>
<br>

<p>Hello,<o:p></o:p></p>
<p>it can be some other limits set in the system, I encountered
also with centos/redhat and couldn't figure out myself (well,
not a sysadmin here). It is the reason I added fork_delay and
modinit_delay. You have to dig in the settings of the system
and try to tune them.<o:p></o:p></p>
<p>Happening can be somehow random, a matter of how busy the
system is at that moment.<o:p></o:p></p>
<p>Cheers,<br>
