ERROR on clear cash fron admin DB

[Dmitry Ermolaev]

I store in cash connection:

# покажем если был вызов а не из кэша
def conn_1(curr, xcurr):
    print 'try connect to ',curr.abbrev
    # def __init__(self, service_url, service_name=None, timeout=HTTP_TIMEOUT, connection=None):
    cn = ServiceProxy(xcurr.connect_url, None, 40)
    #print cn
    blk = cn.getblockcount()
    print 'connected on block:', blk
    return cn

# тут если удача то надолго запомним
def conn_0(curr, xcurr):
    try:
        cn = cache.ram(curr.abbrev, lambda: conn_1(curr, xcurr), time_expire = 36000)
    except Exception as e:
        print curr.abbrev + ' conn except: %s' % str(e).decode('cp1251','replace')
        cn = None
    if not cn:
        cache.ram.clear(curr.abbrev)
    return cn

# если нет связи то тоже запомним на небольшое время
def conn(curr, xcurr, cn=None):
    # пока не подключимся - пробуем
    cn = cache.ram(curr.abbrev + '_0', lambda: conn_0(curr, xcurr), time_expire = 10)
    return cn

Did you upgrade recently? What's in your application's cache folder?

[Kiran Subbaraman]

The appadmin.py may have changed between web2py releases (release1 being the one which you used to create your application initially, and release2 being the one that you want to run your application in now.)
By default this appadmin.py is contained within your application.

So, can you try to copy the appadmin.py from the default "welcome app" of release2, and copy it into your application's controller directory.
See if this sorts out the issue.
