[molpro-user] Molpro not clearing memory

[Jesse Kadosh]

Dear Charles,

Thanks for your suggestion; I just tried ipcs in my cluster's terminal, but it 
lists the following in response:

==========================================================================
------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status
 
------ Semaphore Arrays --------
key        semid      owner      perms      nsems
 
------ Message Queues --------
key        msqid      owner      perms      used-bytes   messages
==========================================================================


/proc/meminfo gives the following information, which may be useful:
