Coolbhai,
If the way your application was designed, it is appending to the file
each microsecond, you must take the risk of loosing some data whenever
you refresh the log file.
If you are appending, then if the file does not exist, the append
will create it.
Here is one possible solution if you want to save the file:
If you do not want to save:

VK_LOGMERGE(1) General Commands Manual VK_LOGMERGE(1)NAME
vk_logmerge - a Valgrind XML log file merger
SYNOPSIS
vk_logmerge [flags and input files in any order]
DESCRIPTION
vk_logmerge is a valkyrie(1) helper. Given multiple log files (in xml format) generated by multiple runs on a parallel machine, or multiple
log files generated by sequential runs on a single-processor machine, for the same binary, vk_logmerge merges the log files together, sum-
ming the counts of duplicates, and outputs the result to a single file. As input, vk_logmerge expects the log-files to-be-merged and/or a
file containing the list of log-files to-be-merged, with each entry on a separate line.
Log files can be merged from within valkyrie(1) , or use can invoke vk_logmerge directly.
OPTIONS -h Show help message
-v Be verbose (more -v's give more)
-t Output plain text (non-xml)
-f <log_list>
Obtain input files from <log_list> file (one per line)
-o <writefile>
File to write output to
At least 1 input file must be given.
If no '-o outfile' is given, writes to standard output.
EXAMPLES
vk_logmerge log1.xml -f loglist.fls -o merged.xml
