I've got a fairly large system (originally written in Delphi, then moved to Kylix, and now finally in FPC 2.2.2) which is doing a lot of different things. Various threads are running which execute reports, communiate with other devices, query data, process notifications, send and receive data on sockets, etc.
For analysis of how its performing, I've got a thread which prints out the information from GetFPCHeapStatus every five minutes. What I notice is that CurrHeapUsed is not growing at all, it stays pretty much the same over hours of running. However, CurrHeapSize is pretty much continuously growing. For example (cu is current heap used, cs is current heap size, cf is current heap free, mu is max heap used, ms is max heap size): heap status: cu=1,407,664, cs=34,930,688, cf=33,523,024, mu=33,621,024, ms=35,749,888 heap status: cu=1,411,264, cs=66,715,648, cf=65,304,384, mu=33,635,232, ms=67,239,936 heap status: cu=1,409,296, cs=98,435,072, cf=97,025,776, mu=33,635,232, ms=98,467,840 heap status: cu=1,411,952, cs=161,873,920, cf=160,461,968, mu=33,674,176, ms=161,873,920 heap status: cu=1,409,056, cs=193,593,344, cf=192,184,288, mu=33,674,176, ms=193,593,344 heap status: cu=1,409,360, cs=193,593,344, cf=192,183,984, mu=33,674,176, ms=193,626,112 heap status: cu=1,409,552, cs=225,312,768, cf=223,903,216, mu=33,674,176, ms=225,345,536 heap status: cu=1,408,704, cs=257,032,192, cf=255,623,488, mu=33,674,176, ms=257,064,960 etc. top shows: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND 15196 root 19 0 2323m 1.8g 2780 S 0 24.6 0:00.68 4 processname free -m shows: total used free shared buffers cached Mem: 7611 7356 254 0 66 5023 -/+ buffers/cache: 2266 5344 Swap: 4094 0 4094 If I were allocating memory and not deallocating it, ie., if it were a memory leak, it seems CurrHeapUsed would be growing, right? It seems I should be concerned... what's the best direction to go from here? HEAPTRC? -SG ======================== Computer over. Virus = very yes.
