hey bill,
thanks for the suggestion. i was trying to install zimbra on two old dell servers i had (just for testing). i think the issue was due to my hardware not beiing sufficient. they were both dual p3 733mhz one with 1gb of ram and the other with 512mb. both of these machines kept spawning the processes until they both completely grinded to a halt from memory exhaustion. however, when i ripped apart my personal computer (ahtlon 64 3800, 2gb of ram) and threw on FC4 with Zimbra, it installed just fine never going above ~120-130 processes.
thanks again for the suggestion even though it was lack of hardware.
