There are error messages in my Mongo 3.1.6 log files
E STORAGE [conn62121] WiredTiger error (22) [1626729151:881686][9515:0x7f8d484f6700], WT_SESSION.timestamp_transaction: __wt_txn_parse_read_timestamp, 930: read timestamp 60f5eabf00000356 older than oldest timestamp 60f5eabf0000035e: Invalid argument Raw: [1626729151:881686][9515:0x7f8d484f6700], WT_SESSION.timestamp_transaction: __wt_txn_parse_read_timestamp, 930: read timestamp 60f5eabf00000356 older than oldest timestamp 60f5eabf0000035e: Invalid argument
What is that mean? Should it be concernerd?
Thanks
Welcome to the MongoDB Community Forums @Michael_Geller!
Per SERVER-38871 and linked issues, this message is informational for a routinely handled scenario that does not require user intervention and should not be a concern.
Is 3.1.6 the correct server version? If so, 3.1.6 is a development release from 6 years ago and definitely not intended for production use. You should upgrade to the final 3.2.22 release as there have been important security and stability fixes.
If the version numbers happen to be transposed and you are actually running 3.6.1, I recommend upgrading to the final 3.6.23 release. The oldest supported production release series is currently MongoDB 4.0, so it is definitely time to start planning your upgrade to a supported release.
