File processing stops on bean invocation at times

I have a simple route as following

from("file:{{input.dir}}?sortBy=file:name詷▹=.*.data骋={{done.dir}}痩={{poll.delay}}")
.id("FileConsumer")
.log("Processing file ${file:name}")
.beanRef("FileBinder","bind")
.beanRef("PU","execute")
.log("Completed processing ${file:name}")
.end();

Running Apache Camel 2.13.1 in Apache Karaf 3.0.0. I have around 100 files
in the input directory. Camel processes 5-6 files initially and then the
second bean invocation doesn't happen and the file processing stops at that
point with no exceptions. I have another Camel route which is using quatrz2
cron like scheduler producing these files in {{input.dir}}. When ever there
is an invocation from quartz scheduler in between the above mentioned route,
the issue happens. What is going wrong here ? The camel trace
MethodInfo.java:276 | >>>> invoking is not appearing for the second bean
invocation.
