IDS Memory leak with tcp connections under high lo

Hello, does anybody know about a memory leak in the shared memory of IDS10 (FC6, FC7) on HPUX 11.31 whith many network connections (and high load)? We have a SAP system with IDS10FC7 with about 1400 concurrent sessions running on HP Superdome HPUX 11.31. Since the switch to the new Superdome with HPUX 11.31 (faster OS network stack!? faster hardware) we see an steady increase (up to a few GB per hour) of global shared memory pool onstat -g mem|grep global And onstat -g afr global shows more and more entries with 'net' (afew hundreds more every second). onstat -g ntu shows a similar increase in the alloc/maxcounters in the header/summary line. Anyone seen something like this? It seems as if the problem is reproducable with simple queries against a sysmaster tables an a small server - although in this case the increase of the counters or shared memory is minimal and would not look very suspectible. Should the net configuration (NETVPs etc.) be changed? onconfig follows - yes, it's a really big machine: ROOTNAME rootdbs # Root dbspace name ROOTPATH /informix/P91/sapdata/physdev1/data1 # Path for device containing root dbspace ROOTOFFSET 16 # Offset of root dbspace into device (Kbytes) ROOTSIZE 170000 # Size of root dbspace (Kbytes) MIRROR 1 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH /informix/P91/sapdata/physdev2/data3 # Path for device containing mirrored root MIRROROFFSET 16 # Offset into mirrored device (Kbytes) PHYSDBS physdbs # Location (dbspace) of physical log PHYSFILE 2000000 # Physical log file size (Kbytes) LOGFILES 2125 # Number of logical log files LOGSIZE 5000 # initial (!)
