Hi Steve I know it's slow, valgrind is checking the memory. Note that I have just fixed some memory leaks that might have caused memory issues.
I suggest you to stop valgrind, send me the dump (or put it somewhere on the internet) and start ntopng again without valgrind so I can analyse your log in the meantime Regards Luca On Aug 28, 2013, at 3:19 PM, Steve Clark <[email protected]> wrote: > Hi Luca, > > I am running ntopng under valgrind, but it ntopng is running so slow I am not > sure > if the error will occur. > > Received Packets 529,228 Pkts > Dropped Packets 67,720,745 Pkts [ 99.22 % ] > > On 08/28/2013 07:38 AM, Luca Deri wrote: >> Steve >> this is not the bug, but the memory was corrupted previously IMHO >> >> the code is >> >> if (jso->_user_delete) >> jso->_user_delete(jso, jso->_userdata); >> >> but as jso->_user_delete = 0 >> >> you should not execute such line. >> >> I encourage you to run valgrind and send me the problems reported >> >> valgrind ./nprobe ….. >> >> so I can look at them.
