I'm using a Raspberry Pi to run pywws, in support of a personal weather station. I noticed that it had stopped working, so rebooted my Pi; however, now I'm getting peculiar errors with simple Linux commands.

Here's an example:-

jeremy@raspberrypi ~ $ ps -ef | grep pywws
ps: error while loading shared libraries: /lib/arm-linux-gnueabihf/libprocps.so.
0: Unable to run arch-specific checks

I've had an unsuccessful Google for this error but with no luck and now I'm stumped.

I've checked the library exists.

jeremy@raspberrypi ~ $ ls -l /lib/arm-linux-gnueabihf/libprocps.so.0*
lrwxrwxrwx 1 root root    18 Mar 29  2013 /lib/arm-linux-gnueabihf/libprocps.so.
0 -> libprocps.so.0.0.1
-rw-r--r-- 1 root root 59308 Mar 29  2013 /lib/arm-linux-gnueabihf/libprocps.so.
0.0.1

Suggestions gratefully received. I hadn't logged onto the Pi for a couple of weeks, so nothing has been consciously changed.

    I think it might be a fault with the SD card. I tried to install htop in order to get some more diagnostics and in the middle of the apt-get output was segmentation fault. If I try to start pywws manually, I get an IOError: open failed. As a result, I'm going to fsck the SD card using another machine. – Jeremy Gooch Feb 26 '15 at 13:15

I did an fsck.ext4, which seemed to find some problems with the SD card. Just to be on the safe side, I rebuilt it. I guess the SD card is on its way out.

The IOError with pywws is a separate issue.
