Daily Quota 1/cpu

Hi, I have run einstein in some computers. Two of them running in freebsd/amd64 (one ver 8.2 release, the other is ver 9.0 release). The computer ID for 8.2 release is 5000175, and the other is 5035644. The 5035644 have no problem at all, but I wonder why computer ID 5000175 have a limit to 1 task/cpu/day? The message was computation errors. All err with "process got signal 4".

thx
