--- Comment #23 from Chloé Desoutter <ch...@tigres-rouges.net> ---
I can trigger crashes after a long while in a heavy workload, quite randomly,
with 256.
Out of curiosity I checked the pmspcv driver from FreeBSD and they use a lower
value still :
#define MPI_MAX_INBOUND_QUEUES 64 /**< Maximum number of inbound
queues */
#define MPI_MAX_OUTBOUND_QUEUES 64 /**< Maximum number of outbound
queues */
/**< Max # of memory chunks
supported */
#define MPI_MAX_MEM_REGIONS (MPI_MAX_INBOUND_QUEUES +
MPI_MAX_OUTBOUND_QUEUES) + 4
#define MPI_LOGSIZE 4096 /**< default size */
so I'll try with this value and give feedback for stability and performance.
