If no information - is found for an item, the page will simply say "No information - found". The reason for not finding any information about an item - can be that the dump is truncated, that it is a dump from an old - OTP release in which this item was not written or that the item - simply wasn't present in the system at the point of failure. - - <p>If the dump was truncated, a warning is displayed. - - <p>Even if some information about an item exists, there might be - empty fields if the dump originates from an old OTP release. - - <p>The value "-1" in any field means "unknown", and in most cases - it means that the dump was truncated somewhere around this field. - - <p>Only some of the fields in the different information pages are - described here. These are fields that to not exist in the raw - crashdump, or in some way differs from the fields in the raw - crashdump. Details about other field can be found in the user's - guide for the Erlang runtime system, in the chapter "How to - interpret the Erlang crash dumps". A link to this chapter can be - found in the Crashdump Viewer's menu under documentation, and - there are also direct links from the specific sections below to - related information in "How to interpret the Erlang crash dumps". - - <a NAME="general_info"> - <h3>General information</h3> - - <p>This is the first page shown when a new dump is loaded into - the system.

The 'Id' is the same as the - 'Table' field found in the raw crashdump, and 'Memory' is the - 'Words' field from the raw crashdump translated into - bytes. 'Type' is the type of table, and it can be either "hash" - or "tree".

The last created atom is listed first. - - <p>Note that if the dump is from OTP R8B or earlier, the raw - dump lists the atoms in the opposite order and the Crashdump - Viewer reverses them.

Visible nodes are alive nodes with a living connection to - the originating node. Hidden nodes are the same as visible - nodes, except they are started with the "-hidden" flag. Not - connected nodes are nodes that are not connected to the - originating node anymore, but references (i.e. process or port - identitifiers) exist. - - <p>'Links/Monitors' may contain information about links or - monitors between processes on the originating node and the - connected node. - - <p>'Extra Info' may contain debug information (i.e. special - information written if the emulator is debug compiled) or error - information. - - <center> - <a href=/crashdump_erts_doc/crash_dump.html#distribution_info> - More...</a> - </center> - - - <a NAME="loaded_modules"> - <h3>Loaded modules</h3> - - <p>The loaded modules information page shows all modules that - were loaded on the originating node, and the current size of the - code.
