SugarChimp

Hello, I am experiencing an error while targets are being pushed from a Sugar list to the corresponding synced Mailchimp list. Small numbers of targets (5, 10, 20) will sync over without issues consistently. However, when I add 40 targets to the Sugar list, the scheduler for the SugarChimp job ceases to run and the status of the job stays at "running" indefinitely (with the records remaining in queue). Here are the last two lines in the log during the unsuccessful sync of 40 targets: [32328][1][FATAL] SugarChimp:debug:1438893602: Run SugarChimp_Job_UpdateMailchimpSubscriber for Prospects [32328][1][FATAL] Job a9fb0ba9-ad38-f008-52cd-55c3c6e86427 (SugarChimp) failed in CRON run This was the output of the log at the same point in the process during the successful sync of 20 targets (which went on until it continued successfully): [719][1][FATAL] SugarChimp:debug:1438894802: Run SugarChimp_Job_UpdateMailchimpSubscriber for Prospects [719][1][FATAL] SugarChimp:warning:1438894802: SugarChimp_FieldMap::get_field_mappings could not find mapping for key 59ff5e4fa7|Prospects.
