Hi:
I installed IDS sds in SUN OS 5.9, I initialize the primary and SDS server successful. I could execute some query from SDS server, But after I ran some applicaton in the primary server, The sds server disconnect from the primary server. In the online.log , IDS report the following error:
12:00:15 Adjusting LRU for bufferpool - id 0 size 2k
12:00:15 Old max 55.9 min 46.6 New max 55.9 min 46.6
12:00:16 ERROR: Removing SDS Node JSPMDBSDS has timed out - removing
12:00:17 SDS Server JSPMDBSDS - state is now disconnected
12:00:21 Checkpoint Completed: duration was 46 seconds.
I cann't query the data from the primary server.
The Primary server configuration are listed in following.

I installed the informix product in share disk. And in the SDS machine, Informix could write the page file and temp dbspace file. The customer has installed most patches.
Could anyone help me to check? It's really little document for reference. thanks
