I changed the following line in logback.xml :

<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
     <fileNamePattern>${LOCATION}${BASE_NAME}_%d.log</fileNamePattern>
</rollingPolicy>

to

<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
      <fileNamePattern>${LOCATION}${BASE_NAME}_%d.log</fileNamePattern>
    <minIndex>1</minIndex>
    <maxIndex>10</maxIndex>
</rollingPolicy>

<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
      <maxFileSize>200MB</maxFileSize>
</triggeringPolicy>

Now I am getting this error whenever my application tries to log :

  at java.lang.IllegalStateException: FileNamePattern [/var/log/iess/abc/abc__%d.log] does not contain a valid IntegerToken
        at      at ch.qos.logback.core.rolling.FixedWindowRollingPolicy.start(FixedWindowRollingPolicy.java:92)

I think you are getting space in date.
Check here sample for data pattern.

Check for <timestamp key="bySecond" datePattern="yyyyMMdd'T'HHmmss"/>

Have you checked out the documentation for that Policy...

http://logback.qos.ch/manual/appenders.html#FixedWindowRollingPolicy

The second paragraph of that section gives you your answer (emphasis added by me)...
The fileNamePattern option represents the file name pattern for the archived (rolled over) log files. This option is required and must include an integer token %i somewhere within the pattern.
Therefore, you need to change the %d in your current fileNamePattern to be %i.
