Restarting may be a temporary workaround but cant be a permanent solution. 
After some days, the problem will come back again.

Hi,
We are facing an issue where Cassandra has open file handles for deleted 
sstable files. These open file handles keep on increasing with time and 
eventually lead to disk crisis. This is visible via lsof command. 
There are no Exceptions in logs.We are suspecting a race condition where 
compactions/repairs and reads are done on same sstable. I have gone through few 
JIRAs but somehow not able to coorelate the issue with those tickets. 
We are using 2.0.14. OS is Red Hat Linux.
Any suggestions?

ThanksAnuj
