Sometimes, aMuleWeb server gives the following error and dies:
amuleweb: ../../../src/libs/ec/cpp/ECTag.h：164：CMD4Hash CECTag::GetMD4Data() const: assertion “(m_dataType == EC_TAGTYPE_HASH16) || (m_dataType == EC_TAGTYPE_UNKNOWN)” fails (Translated from Chinese).

Here is the backtrace:

Anybody can look into this? It seems the returned EC type is sometimes incorrect for hashes. I did print m_dataType in gdb, it shows:
Code: [Select]
(gdb) print m_dataType
$1 = 2 '\002'

According to ECTagType.h, 2 means UInt8. I have no idea how this happens.

It seems when this error happens, the amuled is dead as well. Maybe the bug is caused by somewhere in amuled.

I can think of several scenarios here:
1. Sort of memory overrun in amuled which causes daemon to crash and send corrupted EC data.
2. Bug in EC network layer, which causes corrupted packet to be passed to webserver when other side (amuled) unexpectedly terminates in the middle of transmission
3. Version mismatch between amuled and webserver.

Number (2) is most likely. Try to run amuled in foreground, from terminal and check backtrace and/or error messages.

If #2 is the problem, it should happen to normal gui serving the webserver too.

It might be related to this bug. http://forum.amule.org/index.php?topic=14141.0

I will try to observe one or two days after applying this patch.

In this case, it seems that problem is daemon specific (wrong configuration - too many opened connections)
