Can you send over the log for that one.

It seems that no estimate on message compression is done, but just a regular length estimate. Perhaps the requester should also send a hint on how well the data is expected to compress. Otherwise, the length checking business could be a bit delayed, but that could make the code more complex. > (I'm looking forward to the cleanup which the openAIS integration will > bring here, as making that module pluggable should help untangle it ;-) > > > Regards, > Lars > > -- > Teamlead Kernel, SuSE Labs, Research and Development > SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG N?rnberg) > "Experience is the name everyone gives to their mistakes." -- Oscar Wilde > > _______________________________________________________ > Linux-HA-Dev: Linux-HA-Dev@lists.linux-ha.org > http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev > Home Page: http://linux-ha.org/ -- Dejan _______________________________________________________ Linux-HA-Dev: Linux-HA-Dev@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/
