Hi Al Mamun,

For NW 7.1 and higher systems, the session communication between ICM and
Java Server Node takes place through FCA (Fast Communication Architecture). FCA uses memory pipes as opposed to sockets. Messages are written to and read from memory pipes. This makes the communication faster in FCA.

In your case, it seems that all the memory being utilized for FCA communication has been used and there is no free memory available.

You will need to restart your Java Engine. It will clear all FCA related memory pipes and get your system running correctly. This step is needed as we cannot clear it any other way

Please do the following to avoid this situation

1. Please check ICM parameter settings according to note#737625
   Especially for parameter of icm/max_conn.

2. Check the Instance properties for parameter
   "icm[J2EE]/enable_icmadm = true" according to note#1635058
Please adjust ICM parameters settings to the recommend ones mentioned
in note#737625 and add "icm[J2EE]/enable_icmadm = true" if it is not
maintained according to note#1635058.

3. Please also check the following sap note
   715400  Max. number of memory pipes (MPI) restricted to 4000

Hello

You may refer sap note 1867119  - No more memory for FCA that handles the situation.
