I executed my application which uses a Fb database. Trace log was enabled. There was a strange internal transaction

2015-04-14T10:46:44.6010 (3684:00D0A9F4) START_TRANSACTION

C:\. . .\MYDATABASE.FDB (ATT_0, <unknown_user>, NONE, <internal>)

(TRA_595, READ_COMMITTED | REC_VERSION | WAIT | READ_ONLY)

It stayed active over 6 minutes until I stopped my application.

2015-04-14T10:52:55.0410 (3684:00D0A9F4) COMMIT_TRANSACTION

C:\. . .\MYDATABASE.FDB (ATT_0, <unknown_user>, NONE, <internal>)

(TRA_595, READ_COMMITTED | REC_VERSION | WAIT | READ_ONLY)

      0 ms

There is no other information about TRA_595 in the whole log file. What is that transaction?

Thanks for the information!
