|

- I think this Launchpad discussion is relevant: https://bugs.launchpad.net/ubuntu/+source/ghostscript/+bug/1806517
|
||||
- As well as the original Ghostscript bug report: https://bugs.ghostscript.com/show_bug.cgi?id=699815

|
||||
## 2019-01-24
|
||||
|
||||
- I noticed Ubuntu's Ghostscript 9.26 works on some troublesome PDFs where Arch's Ghostscript 9.26 doesn't, so the fix for the first/last page crash is not the patch I found yesterday
|
||||
- Ubuntu's Ghostscript uses another [patch from Ghostscript git](http://git.ghostscript.com/?p=ghostpdl.git;h=fae21f1668d2b44b18b84cf0923a1d5f3008a696) ([upstream bug report](https://bugs.ghostscript.com/show_bug.cgi?id=700315))
|
||||
- I re-compiled Arch's ghostscript with the patch and then I was able to generate a thumbnail from one of the [troublesome PDFs](https://cgspace.cgiar.org/handle/10568/98390)
|
||||
- Before and after:
|
||||
|
||||
```
|
||||
$ identify Food\ safety\ Kenya\ fruits.pdf\[0\]
|
||||
zsh: abort (core dumped) identify Food\ safety\ Kenya\ fruits.pdf\[0\]

||||

|
||||
identify: CorruptImageProfile `xmp' @ warning/profile.c/SetImageProfileInternal/1747.
|
||||
```
|
||||
|
||||
- I reported it to the Arch Linux bug tracker ([61513](https://bugs.archlinux.org/task/61513))
|
||||
- I told Atmire to go ahead with the Metadata Quality Module addition based on our `5_x-dev` branch ([657](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=657))
|
||||
- Linode sent alerts last night to say that CGSpace (linode18) was using high CPU last night, here are the top ten IPs from the nginx logs around that time:
|
||||
|
||||
```
|
||||
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "23/Jan/2019:(18|19|20)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

|
||||
2378 45.5.186.2
|
||||
```
|
||||
|
||||
- 45.5.186.2 is CIAT and 66.249.64.155 is Google... hmmm.
|
||||
- Linode sent another alert this morning, here are the top ten IPs active during that time:
|
||||
|
||||
```
|
||||
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "24/Jan/2019:0(4|5|6)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

|
||||
8593 45.5.186.2
|
||||
```
|
||||
|
||||
- Just double checking what CIAT is doing, they are mainly hitting the REST API:
|
||||
|
||||
```
|
||||
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "24/Jan/2019:" | grep 45.5.186.2 | grep -Eo "GET /(handle|bitstream|rest|oai)/" | sort | uniq -c | sort -n
|
||||
```
|
||||
|
||||
- CIAT's community currently has 12,000 items in it so this is normal
