--- Comment #1 from Guillaume Castagnino <casta at xwing.info> ---
I have this one too, on my employer's exchange server (imap connector) with a
quite poor connectivity (connection regularly reset, sometime huge network
lag).

When I strace the akonadi_imap_resource, I see that the process is stuck in a
loop:
poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN},
{fd=6, events=POLLIN}, {fd=9, events=POLLIN}], 5, 4294967295) = 1 ([{fd=3,
revents=POLLIN}])
read(3, "\1\0\0\0\0\0\0\0", 16)         = 8
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN},
{fd=6, events=POLLIN}, {fd=9, events=POLLIN}], 5, 4294967295) = 1 ([{fd=3,
revents=POLLIN}])
read(3, "\1\0\0\0\0\0\0\0", 16)         = 8
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN},
{fd=6, events=POLLIN}, {fd=9, events=POLLIN}], 5, 4294967295) = 1 ([{fd=3,
revents=POLLIN}])
read(3, "\1\0\0\0\0\0\0\0", 16)         = 8
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN},
{fd=6, events=POLLIN}, {fd=9, events=POLLIN}], 5, 4294967295) = 1 ([{fd=3,
revents=POLLIN}])
read(3, "\1\0\0\0\0\0\0\0", 16)         = 8
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(6, 0x13f76e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN},
{fd=6, events=POLLIN}, {fd=9, events=POLLIN}], 5, 4294967295) = 1 ([{fd=3,
revents=POLLIN}])


Looking at .xsession-errors file, there is no significant error.  Some messages
like this, but nothing more:
akonadi_imap_resource_0(6697)/kdepimlibs (kimap)
KIMAP::StoreJob::handleResponse: We asked for UID but the server didn't give it
back, resultingFlags not stored. 
akonadi_imap_resource_0(6697)/kdecore (KConfigSkeleton)
