after upgrading from a smooth running zimbra 4.5.7 to 4.5.9_GA_1454 on my Suse 10 Linux box i've trouble with very high iowaits on my machine:
After starting zimbra iowait goes up; no idle time left. after investigation i found the zimbra logger process as source of the problem: stopping the logger everything is ok.
what are the deeper problem behind this symptoms? How can i find out? (there is no heavy traffic on this machine, so there aren't realy IO probs).
thanks for your advise.
