<DIV>Hey,</DIV>
<DIV> </DIV>
<DIV>(kolab 3.3 on debian 7.6)</DIV>
<DIV> </DIV>
<DIV>i noticed segmentation faults in my syslog for ctl_cyrusdb</DIV>
<DIV>grepping for them I noticed they happen, happen again 30mins later</DIV>
<DIV>and again 2hrs after the first one (or 1.5 after the second)</DIV>
<DIV> </DIV>
<DIV>here a copy/paste from the syslog with grep for the fault</DIV>
<DIV> </DIV>

<DIV> </DIV>
<DIV>I then looked in the syslog what is occuring at those times. i found
checkpointing immediately proceeds the segfault.</DIV>
<DIV> </DIV>
<DIV>so I grepped for it:</DIV>

<DIV> </DIV>
<DIV>I found that the checks happen every 30minutes</DIV>
<DIV> </DIV>
<DIV>when they complete I get:</DIV>

<DIV> </DIV>
<DIV>but as we can see above, every 30+90 minutes they fail. there I get:</DIV>
