[horde] Horde + imp + turba with mysql cluster 5.0.16

[Imanol Apaolaza Sanz]

Hello,

    We are trying to setup a webmail with horde and imp with a mysql 
cluster backend for session handling.
   
    We have no problem with a single mysql, but if we try to use a mysql 
cluster, we recieve the error:

"ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting transaction"

Increasing "TransactionDeadlockDetectionTimeout" MySQL parameter don't 
fix the problem.

Have anyone another type of session high availability for Horde?

Any idea?

Regards
