So the quota file was corrupt. Ok. Do you really use DB4 quota files?

No. In fact they are not errors but informational messages, so in newer 
versions of cyrus imapd you will see

Jul  8 15:39:28 atlanta lmtpunix[29159]: [ID 366844 local6.info] DBMSG: 
2279 lockers
Jul  8 15:51:34 atlanta lmtpunix[29077]: [ID 366844 local6.info] DBMSG: 
2249 lockers
Jul  8 18:12:14 atlanta lmtpunix[4289]: [ID 366844 local6.info] DBMSG: 
1583 lockers

lmtpunix wants to open delivery.db which normally is a DB4 backed 
database unless you have changed the default in imapd.conf.

Some old DB4 version had the problem of not releasing these locks so 
there was an overflow after some time. If the number of lockers keep 
growing without every becoming smaller from time to time you are running 
in this bug.
