Zimbra 4.5.7+High CPU usage with Thunderbird+Lightning.
Many users(including myself) are having problems with Zimbra 4.5.7(Network Edition). Problem occurs when starting Thunderbird(depending on machine) 1-4 minutes thunderbird is slow and unusable. Same problem occurs when reloading remote calendar.
Same case with Sunbird(High CPU usage, Memory usage about 300-400MB)
Tried 4.5.6 everything works fine(Free edition).
Both systems run on Centos5.
When this slowness occurs server load is about 1-4%.
Outlook connectors (on 4.5.7 NE) are working fine.
Any help would be appreciated.
same here -- possible calender corruption bug
I am having the same problem and so are several of my users. Currently we are using 4.5.4 and ever since Lightning 0.5 arrived I personally started experiencing the problem (near 100% CPU and huge memory usage up to 1.3GB) when I first switched to Lightning 0.5. This problem appears to be specific to the user's calendar though as I am able to load another calendar for a shared role account that I use and it has no problems. Lightning 0.7 has the same problem and so does SunBird 0.7. This occurs on Linux, Mac and Windows XP.
Other users in the office have started to report the problem as well.
I am willing to help out with any testing that might help -- but I don't think it is worth exploring verbose modes for IMAP as this problem is independent of Thunderbird and is related directly to Zimbra and Sunbird.
In my case at least the problem appears to be that I have a very strange calendar entry which has around 773,000 lines which look like this: " \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n \n\n\n\n\n\n\n\n\n\n"
This is the very first calendar entry I have and if I try to view it (or delete it) via the web ui, I get the standard firefox browser popup error about a runaway script.
It seems to me that the calendar entry has been corrupted by something. How can I fix this?
