It's very nice to see we are not alone with this problem. We hate this problem since 9.0.1,
IBM Tell us FP2 will solve the problem, problem still present
IBM Tell us FP2HF* will solve the problem, problem still present
IBM Tell us FP3 will solve the problem, problem still present
And so on !
We are currently running with FP4HF523 and the problem is still there.
We have a cluster of 4 serveurs with 6000+ mailfile on each of them... each days, all serveurs choose randomly 1,2,3 or more database to lock.
On my side, 99% of the time, if I run on the console "tell clrepl quit" followed by "load clrepl" to restart the cluster replicator, it solve the problem !
I hope this will be solve in 2016 !
