SYMPTOM(s):
Replication agent dies with SYSTEM ERROR: lkrels record <recid> not locked. (435)
Replication agent will crash when processing recid over 4 billion range
Replication agent crashes when processing recid over 4 billion (2^32) range
recid reported by the 435 message is the id of the record recently created on target database /minus/ 4 billion.
After the 435 errors appear, the target crashes with error 6495 5028
Out of free shared memory. Use -Mxs to increase (6495)
SYSTEM ERROR: Releasing regular latch. latchId: 14 (5028)
latch 14 is "Lock Table Free List" in error 5028
Synchronisation fails after target is restarted 1028 8999
Replicaiton synchronization point fails with following errrors:
SYSTEM ERROR: Rollforward Apply AI note, BKUPDCTR=2, note updctr=1. (1028)
area <areanum>, dbkey 4294967296, record type <recordtype> (8999)
Function dsaAIApplyNote failed in rpNOT_ProcessNoteBlock with error -30000. (10428)
Block processing ended in error at block <block> in area <areanum>. (10495)
Unexpected error -30000 returned to function rpAGT_AgentLoop. (10504)
after target database is recreated from a source backup, replication agent continues to throw error 435
FACT(s) (Environment):
OpenEdge 10.1x
OpenEdge 10.2A
All Supported Operating Systems
CAUSE:
Bug# OE00181622
CAUSE:
A product limit: OE replication crashes when the High-Water Mark (HWM) in an area reaches 4 billion (2^32). Furthermore, each error 435 causes 64 bytes of memory leaks. As result the target is periodically (each a few hours) crashed with error 6495
FIX:
Upgrade to 10.1C04 or 10.2A01 or higher OpenEdge release where this issue has been addressed.
Workaround:
Re-organise the database schema by moving objects out of the storage area affected, into new storage area(s) so that the 4 billion rowid's is not reached. Then remove this storage area and re-baseline replication (ie: re-create the target database)
