ODBC DataServer : My program crashes once per day

After migrating to new Win 2008R2 server one time per day my program stops with following stack-trace (attached below).

This is small ChUI-program, connected with ODBC Dataserver (and via dataserver to Sybase). This is universal adapter for integration purposes, and I have three instances (same code, but different dataserver connection) - for Sybase (ODBC DataServer), for MS SQL (MSS Dataserver) and for Oracle (Oracle DataServer).
I have problems only with one of them - with ODBC Dataserver.

OE version is 10.2B0836/win32

DataServer configured for remote connection and resides on same server as an adapter.

All Sybase queries are simple  (gb - is an alias to foreign db);

    lp:
    REPEAT WHILE AVAILABLE tt:
        DO t-idx = 1 TO 100 WHILE AVAILABLE tt TRANSACTION ON ERROR UNDO lp, leave lp:

               FIND FIRST gb.InterfaceTable1 WHERE ... EXCLUSIVE-LOCK.

               FIND FIRST gb.InterfaceTable2 WHERE ... EXCLUSIVE-LOCK NO-ERROR.
               IF NOT AVAIL gb.InterfaceTable2 THEN DO:
                   CREATE gb.oss_gb_callback.
                      ASSIGN
                          gb.InterfaceTable2.id = gb.InterfaceTable1.id
               END.
               ...
               gb.InterfaceTable1.integration_status = tt.integration_status
    END.
