Hi, I have a setup where 4 ZEO clients running on separate machines connect to a single DB server which runs on a different system by itself. The ZEO clients and the DB server all are at version ZODB3-3.10.2. Now, since the last few weeks some of our users have been reporting that they occasionally see incorrect images being returned.
On googling I came across the thread below and was wondering whether I am seeing the same thing as this: https://mail.zope.org/pipermail/zodb-dev/2011-February/014067.htm ...although the setup and version is different (ie: ZODB-3.8 and RelStorage). Unfortunately, sorry but I do not know enough about ZODB internals to be able to say for sure. Is there a way I can test whether the problem is indeed with the wrong blob file being returned from the blobcache ? FWIW, we haven't figured out a way to consistently reproduce this error ourselves. Other things that may/may-not be relevant: a. our site is image heavy (36293 blob files) and the servers are behind a load balancer so in a single request to the web-app (a repoze.bfg site) we might even load collectively 20+ blobs from any of the 4 servers. b. zeo connection string on the clients zodb_uri = zeo://xxx.xxxx.xxx.xxx:8886/?blob_dir=%(here)s/../var/blobs&shared_blob_dir=false&connection_pool_size=50&cache_size=1024MB&drop_cache_rather_verify=true c. $ cat var/blobs/.layout zeocache Any comments/suggestion on how to isolate and fix this problem would be appreciated. cheers, - steve -- random spiel: http://lonetwin.net/ what i'm stumbling into: http://lonetwin.stumbleupon.com/ _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
