Hi,
We are maintaining the different versions of data in git
repository using jgit maven library. So, a commit is done on the repository
containing properties such as author name, date and time, action, and the file
path.
The file path refers the xml file which contains the
action performed and is stored inside the repository.
We have a job running every 5 minutes that commits the
information onto the repository and the XML file content is over-written every
time. Usually, the commits and writing of XML file takes around 4-5 seconds but
sometimes the time while committing as well as writing the data increases which
also increase the overall CPU utilization of the machine. This behavior is
inconsistent with respect to the process and occurs randomly but during this
behavior, there is a time when the CPU utilization becomes high that all other
running processes hangs up which demands the restart of the server.
Furthermore,
>> The XML files that are being written as content
are multi-line. There are 2 tags present in the file and each tag are on their
own line (one tag being the child of the other). The file size isn't large. It
is hardly 2-3kb. Below is the sample structure of the XML file being added as a
part of content:
<?xml version="1.0"
encoding="UTF-8" standalone="yes"?> <ServiceName
type=ServiceType> <property>PropertyValue</property>
</ServiceName>
>> There are no virus scans running in the
repository. Also, the git LFS isn't involved in this scenario.
>> There might be a case as when the commit time
starts increasing (initially from 4-5s to 30s to 1min to 6-7min) and during
that time another commit call also starts as there is a scheduler of 5 minutes
which triggers this action. But this will only cause a certain amount of delay
and it shouldn't be the factor to increase the CPU Utilization.
Also, the machine memory size is 32GB and the machine
type is /dev/nvme2n1
The commit time starts increasing from 4-5s and goes up
to 6-7mins, what could be the trigger for the commit to increase from 4-5s to
1min and so on in this scenario since before that there can't be any parallel
commits ongoing onto the repository? Also, as I mentioned before, this issue is
totally inconsistent.
Let me know in case any other information is required.
Could you please suggest which areas should we look for
while identifying the cause of this issue? Also, does frequent commit of the
content onto repository can trigger this issue?
In your view, what might be the trigger of this issue and
how we can proceed to resolve it?
Thanks & Regards,
Arpit Gupta
