NXLog 4.3.4308 failed to open files

Hi everybody!

Today I found in the logs of NXLog 4.3.4308 Server very odd error:

2019-06-12 11:22:04 ERROR failed to open file <FILE> when trying to truncate: Too many open files

The service was not working at this time until I has restarted it.

Could you be please so kind tell me what is the limit of opened files? What's the number simultaneous connections can the service hold?

Error: incorrect header check

Hi everybody,

I have a very mystical case and I need your help, please:

  1. I have nxlog server nxlog-3.2.2016-1.x86_64
  2. I installed a update to latest version of nxlog server (nxlog-4.1.4016-1.x86_64)
  3. Config for clients was not change.
  4. In the logfile of nxlog server I see many errors and nxlog do not save data:

2018-09-25 10:50:32 ERROR zlib decompression error, data error (Z_DATA_ERROR) incorrect header check

ERROR ### ASSERTION FAILED at line 206 in om_dbi.c/om_dbi_get_sql(): "len > j" ###

We're testing nxlog and at least a few times per day it's throwing this error. When this happens the error repeats itself in the logs for a few hours until either the log fills up the  partition or the kernel kills nxlog due to memory running out (Out of memory: Kill process 2422 (nxlog) score 762 or sacrifice child).
