Event_log shows the following error:
Error 2013-01-30 00:30:30.951845 15816 639002368 Reader: Reader missed a marker, waiting for 25555002 but got 25555005, Restarting to make sure we're querying from proper snapshots. Record from seqno/offset : 7866/80570384 (from xxxxx) [module ord]
The reader marker file ($SP_SYS_VARDIR/state/marker) did not get flushed from memory to disk due to a server crash, a failover or a disk issue. Upon startup, the read process resumed reading from an old marker file.
STATUS:
Issue fixed in version 6.1.1.23.
The latest version of SharePlex can be downloaded at: https://support.quest.com/shareplex/download-new-releases
WORKAROUND:
1. Stop reader:
sp_ctrl > stop read
2. Add positive number like 100-10000 to the marker reader is looking for in the event_log, then replace old number with the higher number.
Example:
Go to $SP_SYS_VARDIR/state directory
Look for o.SID.marker file.
Replace the old number with 25555005 (25555005+10000=25565005)
3. Start read :
sp_ctrl> start read
Note : In 7.6.x and higher, SharePlex automatically restarts to make sure it is querying from proper snapshots.
