Malloc_consolidate(): invalid chunk size

Hi. Faced with a server crash of the following type:

The error specifies the PID = 2046343. But the TID = %bd is unclear)
PID = 2046343 it was http. The last entry from the http task is as follows:
[2046343:000018-00007839F17FB700] 26.06.2025 17:52:59 http: salimovaen@organic.com [10.27.186.12] authentication failure using internet password
[2046343:000018-00007839F17FB700] 26.06.2025 17:52:59 http: CN=Ekaterina Salimova/O=organic [10.27.186.12] has just been locked out via internet password lockout: User is locked out

The main problem is that the NSD didn’t start up as a result. Does anyone have an understanding of what caused the problem, how to debug it, and how to avoid a repeat?

Hi Aleksandr,

This might be a one time event, Please check if you have this notes.ini parameter DEBUG_CHECKMARKERS=1 , It is a special debug created to aid in troubleshooting memory corruption caused by a memory overwrite. To better understand the cause, it is advisable to have the NSD logs.

I do not have the DEBUG_CHECK MARKERS=1 parameter set. Is this parameter related to the fall? Regarding the NSD, I said that in fact the NSD does not start after this error!

This seems a server crash due to memory corruption. Debug_Checkmarkers=1 can help detect the point of corruption. As soon as the corrupt memory block is encountered, the server will crash and will generate an NSD file. You may create a support case and provide all relevant logs for further investigation.

Thanks and Regards
