Re: [BackupPC-users] high load and stuck processes
2010-03-04 17:57:20
Hi Les,
Thanks for the reply.
As i mentioned in my mail, the server has 8gb ram. It has a adaptec 3405 8 port raid card with sata drives ( 8 x 750gb - raid 5).
Right now the maxbackups is set to 8 (i did this thinking the server was powerful enough to handle that many number of clients at one shot). Another reason being, there are like 100+ clients in the network, so if the number of too low, then all clients might not get backed up. Will try the setting and see if anything changes.

trees might be filling memory and making the server swap to the point
that you give up before it is able to respond. It might help to take
$Conf{MaxBackups} down to 1 or 2.
