sql returns fail for some stop requests

[Amir Tal]

Freeradius ver 2.1.12, configured to use ldap for auth, sql for acct.

Sometimes users' sessions get stuck and have to be closed manualy (simultaneous use is turned on for all users).
After extensive debugging I have found the following in the logs (radius -X)

It seems the last SQL query line is cut off for some reason, this only happens on some connections, while others are stopped correctly.
Not specific to users or time of day.
