My splunk services wont start 

06-17-2020 11:13:37.100 -0400 ERROR BTreeCP - open failed to restore checkpoint in btree='/opt/splunk/var/lib/splunk/fishbucket/splunk_private_db', it may be corrupted -- run `SPLUNK_HOME/bin/btprobe -d '/opt/splunk/var/lib/splunk/fishbucket' -r` to attempt to repair

This splunk is enterprise security plus heavy forwarder and has version 7.x on it. All my other servers are on 8.x.

Due to lot of dependencies on python 2.7 we did not upgrade this one but it worked fine for many months.

Did you run the btprobe command as suggested?

[hrithiktej]

Yes but i get the following

[root@dc1-splunk02 bin]# ./btprobe -d
/opt/splunk/bin/splunkd: error while loading shared libraries: libjemalloc.so.2: cannot open shared object file: No such file or directory
