plz answer soon
Well,
Tuning a kernel parameter is dependent on a lot of things. Actually, the nkthread parameter specifies the maximum number of threads that all processes combined can run at any given time. This is system wide approach. Actually, do we have the default parameter now in setup? It should be (nproc*2)+ 15 or 16 by default I guess.
Also, what is the exact issue you are facing now? Were there any updates done before you experience this issue? What is the OS relase and memory you have in setup?
We also need to make sure that this issue is not because of anything else before you modify the parameter. I'm not sure if the modification of this parameter would help here, however, more information in this regard would help anyone who's gonna address this issue in this forum!

testparm
TESTPARM(1) User Commands TESTPARM(1)
NAME
testparm - check an smb.conf configuration file for internal correctness
SYNOPSIS
testparm [-s] [-h] [-v] [-L <servername>] [-t <encoding>] {config filename} [hostname hostIP]
DESCRIPTION
This tool is part of the samba(7) suite.
testparm is a very simple test program to check an smbd(8) configuration file for internal correctness. If this program reports no
problems, you can use the configuration file with confidence that smbd will successfully load the configuration file.
Note that this is NOT a guarantee that the services specified in the configuration file will be available or will operate as expected.
If the optional host name and host IP address are specified on the command line, this test program will run through the service entries
reporting whether the specified host has access to each service.
If testparm finds an error in the
smb.conf file it returns an exit code of 1 to the calling program, else it returns an exit code of 0. This allows shell scripts to test
the output from testparm.
OPTIONS
-s
Without this option, testparm will prompt for a carriage return after printing the service names and before dumping the service
definitions.
-h|--help
Print a summary of command line options.
-V|--version
Prints the program version number.
-L servername
Sets the value of the %L macro to servername. This is useful for testing include files specified with the %L macro.
-v
If this option is specified, testparm will also output all options that were not used in smb.conf(5) and are thus set to their
defaults.
-t encoding
Output data in specified encoding.
--parameter-name parametername
Dumps the named parameter. If no section-name is set the view is limited by default to the global section. It is also possible to dump
a parametrical option. Therfore the option has to be separated by a colon from the parametername.
--section-name sectionname
Dumps the named section.
configfilename
This is the name of the configuration file to check. If this parameter is not present then the default smb.conf(5) file will be
checked.
hostname
If this parameter and the following are specified, then testparm will examine the hosts allow and hosts deny parameters in the
smb.conf(5) file to determine if the hostname with this IP address would be allowed access to the smbd server. If this parameter is
supplied, the hostIP parameter must also be supplied.
hostIP
This is the IP address of the host specified in the previous parameter. This address must be supplied if the hostname parameter is
supplied.
FILES
smb.conf(5)
This is usually the name of the configuration file used by smbd(8).
DIAGNOSTICS
The program will issue a message saying whether the configuration file loaded OK or not. This message may be preceded by errors and
warnings if the file did not load. If the file was loaded OK, the program then dumps all known service details to stdout.
VERSION
This man page is correct for version 3 of the Samba suite.
