Hi folks,
we have a little setup of a cluster running RedHat with two apaches, memcache, tomcat and some DB machine. We get our php errors send to us per mail.
I observe an increasing rate of mail containing this error message (some values are deleted due to sensitive data).
Code:
Could not save value a:19:{s:7:"";s:1:"0";s:5:"";s:1:"0";s:4:"";s:1:"0";s:4:"";s:1:"0";s:4:"";s:1:"0";s:10:"ADRQUALITY";N;s:13:"ADRVALIDATION";s:1:"0";s:9:"ISCOMPANY";b:0;s:9:"GEBURTDAT";N;s:5:"BERUF";N;s:13:"BERUFPOSITION";N;s:12:"IDKATBRANCHE";N;s:14:"LASTCHANGEDTXT";s:64:"Letzte ";s:5:"";N;s:3:"";N;s:6:"";N;s:5:"";N;s:8:"";N;s:13:"";N;} with key: apacheDocumentRoot_ADDRESS_16752618_ to cache! Cachebackend not available OR instance to large (1MB). Size: 441 bytes.
A search on the net brought nearly nothing. Only a bit of hint to Zend (what we use) but in different wording. "Cache/Backend" instead of "Cachebackend" and this is all they have in common.
Beside not exactly knowing what really trigger the errors the error message is clear to me but can't believe it

Taken apart it tells that either the size is to big (which tippels over for 441bytes beeing lower than allowed size of 1MB). Nother part would be the "Cachebackend not available" but if this would hold true we also would have lost our session (running on the same memcache).
Is there a way to get memcache do some logging? Maybe lost connections or out of memory?
Be glad for any input
Best Regards Zhjim
