Hi
Please find the attached image, which shows CPU & RAM usage by the rrdtool. It looks like some dead lock happened among rrdtool instances. Is anyone can help us to resolve this issue? Whether rrdtool logs any debug messages?

Please find more details for the problem: 1. rrdtool version used - 1.2.28, RAM space available : 128 MB 2. rrdtool update is called using the Linux system call ( popen) from the application thread at every 15 sec for each rrd file ( maximum 20 rrd files) 3. rrdtool Graph is called using the Linux system call (popen) from the apache module at every 1 min if web page is opened. 4. After some runtime, >6 rrdtool instances are active and takes 50-60% RAM and causing the system to hang Please help us, how to avoid more rrdtool instances and more RAM usage. Is there effective way to call rrdtool functions. Regards, Jeeva
