Warning in message log after tuning CLEANERS

Hi guys, I saw the following message in message log after I modified CLEANERS from 18 to 128 and LRUS from 64 to 128 We have enough big Logical Log(640 MB) and Physical Log (40 MB) 09:36:13 WARNING! Physical Log size 0 is too small. Physical Log overflows may occur during peak activity. Recommended minimum Physical Log size is 20 times maximum concurrent user threads. 09:36:13 WARNING! Logical log layout may cause OnLine to get into a locked state. Recommended smallest logical log size is 2 times maximum concurrent user threads. 09:36:14 INFORMIX-OnLine Initialized -- Shared Memory Initialized. 09:36:14 Physical Recovery Started. 09:36:14 Physical Recovery Complete: 0 Pages Restored. 09:36:14 Logical Recovery Started. 0 Committed, 0 Rolled Back, 0 Open, 0 Bad Locks 09:36:17 Onconfig parameter CLEANERS modified from 18 to 128. 09:36:17 Onconfig parameter LRUS modified from 64 to 128. What is the reason? After setting CLEANERS to 64 I didn't see those messages again?
