The following issue has been observed multiple times, considering the following architecture:

• Application with 3 threads, T1@10ms, T2@500us and T3@500us
• T1 has a ConstantGAMT1 with two variables 'StatusDoneT2' and 'StatusDoneT3';
• T2 has a MessageGAMT2 which, on a given event A, writes to T1.ConstantGAMT1.StatusDoneT2;
• T3 has a MessageGAMT3 which, on a given event B, writes to T1.ConstantGAMT1.StatusDoneT3;
• Both events A & B can happen simultaneously or within a very small time interval.

Commonly observed issues (see attached printscreens):

• Segmentation Fault;
• EventConditionTrigger Thread in bad termination stage -> Blocked application;

Temporary solution:

• Split ConstantGAMT1 in two ConstantGAM, one for variable 'StatusDoneT2' and another for 'StatusDoneT3' and modify the variable paths on the MessageGAMs accordingly. After this modification, the reported issues were no longer observed (so far).
