System call error: No such file or directory 11062 - can't rename tcache.new to tcache.a (4319867)

Reader exits because it is unable to rename the tcache file

Issue is caused by system interrupts. Changes were made to 5.3.0 that help resolve this.

Workaround is to manually rename both tcache.a and tcache.b to .old.

Steps for renaming the tcache files.
1) sp_ctrl> stop read
2)
cd $SP_SYS_VARDIR/state
ls *tcache*
and move all the tcaches to .old

mv *tcache*a tcache_a_old
mv *tcache*b tcache_b_old


Once the tcache has been moved.

sp_ctrl> start read

Additionally, check to see if the issue is on OCSF2. If it is, then have the no interrupt option turned off.
