Please show us the last two lines in your input file that were successfully processed by awk and the next three lines in your input file.
Also, please show us the output you get from gawk for those five input lines and the exact text of the diagnostic message that is printed when awk fails.
gawk output for just the five lines: awk output for just the five lines:

Does awk still fail if you only feed it the above five lines; or does it only fail if it has already processed the first 141K lines?
Yes awk failes with just the above five lines.
Quote:
With the above requested information, maybe we can trace through what is happening with the line that is failing in awk.
awk seems to be struggling with several lines after the last successful line.
I put this line all by itself in a file and got segmentation fault: BBN Communications:128.1.0.0-128.1.255.255
I also put this one in file all by itself and got segmentation fault: Lawrence Berkeley National Laboratory:128.3.0.0-128.3.255.255
As well with this one: University of Maryland:128.8.61.128-128.8.61.255
Again, this is the file I've been downloading and using: iblocklist

Hello everybody,
I'm coding a network program and i need it to "understand" ip ranges, but i don't know how to make to parse an IP CIDR range, let's say "172.16.10.0/24" to work with the specified IP range.
I've found a program which does it, but i don't understand the code. Here is the... (3 Replies)
I have a list of about 200,000 lines in a text file that look like this:
1 1 120
1 80 200
1 150 270
5 50 170
5 100 220
5 300 420
The first column is an identifier, the next 2 columns are a range (always 120 value range)
I'm trying fill in the values of those ranges, and remove... (4 Replies)
Hi,
I have two files
file1 chr1_22450_22500
chr2_12300_12350
chr1_34500_34550
file2 11000_13000
15000_19000
33000_44000
If the file 1 ranges fall between file2 ranges then assign the value of file2 in column 2 to file1
output:
chr2_12300_12350 11000_13000
chr1_34500_34550 ... (7 Replies)

Hi all, I would appreciate if someone could share how to convert CIDR notation to netmask and vice versa.
The value below is just an example. it could be different numbers/ip addresses.
Initial Output, let say file1.txt
Final Output, let say file2.txt (3 Replies)
Hi,
Recently I had to convert a 280K lines of ip ranges to the CIDR notation and generate a file to be used by ipset (netfilter) for ip filtering.

001.000.064.000 - 001.000.127.255 , 000 , XXXXX

Weary of seeing our load average go up to 50+, I just did a major block on these networks (stats over a less than 20 min interval):
