Code:
sed -ne '4,$s/GMDCOM.27936//p' input_file

@ Ravinder: Please note that your code is not performing substitution.

Thanks greet_sed for noticing that, here is an awk approach for same.

Code:
awk '
NR==1 || NR==2 || NR==3 || NR==4 {next}
sub("GMDCOM.27936 ",X)' file_name


Output will be as follows.

Code:
[Tue Oct 1 13:37:38 2013]: Process Request <36812985>

No need of calling sub function.

Code:
$ awk '/Process Request/{$1="";print}' file

OR
Code:
$ grep 'Process Request' file | cut -f2- -d ' '

Results
Code:
[Tue Oct 1 13:32:40 2013]: Process Request <36812974>
[Tue Oct 1 13:37:38 2013]: Process Request <36812985>
[Tue Oct 1 13:37:53 2013]: Process Request <36812986>

OR

Code:
echo "GMDCOM.27936 [Tue Oct  1 13:32:40 2013]: Process Request <36812974>"|sed 's/.*\(\[Tue*\)/\1/'
