[rrd-users] rrd_update_r memory corruption

[Erik Torres Serrano]

Hi, I'm having problems with RRDtool and threads. I'm using the Boost C++ library to handle threads and I'm having a memory corruption error at execution time. I'm including the error report at the end of my message. To reproduce this behavior, create a new thread and call the rrd_update_r function in the new thread.

Best regards,

Erik
